A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
https://reuse.software/faq/
BKE_image_ensure_tile_token took only the file name component but used
FILE_MAX to limit the input buffer.
Split this function in two, one that takes the full path as this is the
most common usage and another which takes only the filename.
Both now take a string size argument.
There's been a handful of reports where "obviously" not a UDIM filenames
were detected as such during image open.[1]
This change makes the detection less aggressive by enforcing that the
4-digit sequence be delineated on both sides by one of the following 3
characters ., -, _
This fixes the problem for such filenames as:
"screenshot-1080p.png", "Image-1920x1080.png", "(1999) Photo.png", and
"antiguaChestnut_X_1240Wx814H.png"

There are some filenames where the UDIM pattern guessing would fail
unnecessarily. The user can fix these up afterwards but it would be
nicer if they would detect properly in the first place.
Examples:
`test.1001.ver0023.png` would guess wrong since it uses the image
sequence detection code which finds the first sequence from the end. It
would guess `filename.1001.ver<UDIM>.png`
`uv-test.u1_v2.png` would fail detection due to a bug in the processing.
Make this much more reliable and add tests for the most important tile
related get/set/detection functions.
